  FIG. 2 is a block diagram showing an example of a schematic configuration of the mobile phone according to the embodiment of the present invention. FIG. 3 is a front view showing an example of an external configuration of the mobile phone. The cellular phone 10 according to the present embodiment includes a main control unit 120 serving as a control unit, an internal memory 121 serving as a storage unit, a wireless communication unit 122 serving as a communication unit that performs communication via the cellular phone communication network 20, and an antenna 112. A display unit 125 as a display unit, and a key operation unit 126 as an operation unit.

  The main control unit 120 includes, for example, a CPU, a cache memory, a ROM, a system bus, and the like, and transmits and receives data to and from each unit such as the internal memory 121 and the wireless communication unit 122 by executing a predetermined control program. And control each part. The main control unit 120 is connected to a microphone 108 as a sound input unit and a speaker 109 as a sound output unit via a sound signal processing unit 123. Further, a display unit 125 is connected to the main control unit 120 via a display control unit 124 as a display control unit. Further, the main control unit 120 is also connected with a key operation unit 126 operated by a user when instructing various processes or inputting various data.

  The internal memory 121 is constituted by a semiconductor memory such as a RAM or a ROM, and stores a control program executed by the main control unit 120 and various data. As these storage means, instead of the internal memory 121, a storage medium such as a memory card or an IC card that can be attached to and detached from the mobile phone body may be used.

  The display control unit 124 controls to display an image on the display unit 125 based on the drawing data sent from the main control unit 120. The display unit 125 is configured by using a display 110 including a liquid crystal panel and displays various images based on image data stored in the internal memory 121.

  The speaker 109 receives an analog signal converted from a digital signal by the sound signal processing unit 123, and outputs a voice during a call, or outputs a mail ringtone, a telephone ringing tone, music, or the like. The sound generation means including the speaker 109 and the sound signal processing unit 123 is controlled by the main control unit 120 so as to reproduce and output sound effects and music (music, melody) corresponding to pictograms included in the received mail. can do.

  As shown in FIG. 3, the speaker 109 is configured by separately providing a receiver speaker (receiver) 109a for listening to a voice during a call and an external output speaker 109b for outputting a ring tone or music. Alternatively, a single speaker may be used so that both the speaker for the receiver and the speaker for external output can be used together.

  The key operation unit 126 includes a data input key (ten key, * key, # key) 103, a call start key 104, a call end key 105, a scroll key 106, a multi-function key 107, and the like. This is used when instructing the end of conversation, menu selection, display mode switching, etc., or inputting information.

  The microphone 108 converts the user's voice into an electrical signal (analog signal). An audio electrical signal (analog signal) output from the microphone 108 is input to the sound signal processing unit 123 and converted into a digital signal.

  Next, a description will be given of the control when displaying the message text of mail such as pre-send mail, sent mail, and received mail on the display unit 125 in the mobile phone 10 having the above configuration. In this embodiment, based on an instruction from the user, the message text is displayed so as to flow while being sequentially added from the top. If the additional display character portion consisting of one or more characters that are additionally displayed in the message body corresponds to a preset keyword, the graphic image corresponding to the keyword is sequentially enlarged and displayed on the message body. Control to do.

  The graphic image is, for example, an animation image in which a display image changes with time, or a three-dimensional image that is three-dimensionally designed and viewed three-dimensionally. The graphic image may be a three-dimensional animation image obtained by combining the animation image and the three-dimensional image. This three-dimensional animation image is an image in which a three-dimensionally displayed three-dimensional object image changes so as to enlarge or reduce, or changes so that the object image rotates.

  Table 1 shows a keyword that is determined whether or not it exists in the message body, a graphic image that is overlaid when the keyword is present, and a display of the message body after the graphic image is displayed. The correspondence with the character when returning to is illustrated. As shown in Table 1, a plurality of keywords (pictograms, texts, emoticons) showing similar appearances or concepts are associated with a three-dimensional animation image that is one graphic image representing them. For example, in the message body, a 3D animation image with the sun as the motif is associated with the pictograms of the sun, the sunrise landscape, and texts such as “morning”, “sunny”, and “good morning”. Yes.

  The three-dimensional animation image is enlarged and displayed for a predetermined time set in advance in the center of the display screen displaying the message text so that the user can easily see the three-dimensional animation image. The three-dimensional animation image may be initially displayed in a small size at the center of the screen, and close-up display may be performed so that the size gradually increases so as to approach the user side. The three-dimensional animation image may be displayed so as to cause a three-dimensional movement such as rotation. When the display of each 3D animation image ends, it may be stopped immediately to display the 3D animation image corresponding to the next keyword, or it may be faded out and displayed to gradually reduce the display size. Good.

  When the display of the 3D animation image is finished, the keywords (pictograms, text, emoticons, etc.) corresponding to the 3D animation image that has been displayed up to that point are returned to their original positions in the message body, and the rest of the message body is displayed. Will be added and displayed sequentially. If the keyword corresponding to the three-dimensional animation image is a pictograph, the pictograph obtained by reducing the three-dimensional animation image is returned to the original position in the message body as the final display character. On the other hand, when the keyword corresponding to the 3D animation image is text or emoticon, unlike the case of the above-mentioned pictograms, the difference in appearance from the 3D animation image is large. It is returned in the message body as a display character. This prevents a gap between the message body displayed after the display of the three-dimensional animation image is completed and the original message body from becoming large.

  FIG. 4 is a flowchart showing an example of control in an operation mode (hereinafter referred to as “graphic mail display mode”) for analyzing a message text of a display target mail and displaying a graphic image (three-dimensional animation image). The user of the mobile phone 10 operates the key operation unit 126 so as to instruct mail display such as received mail. The main control unit 120 receives a mail display instruction from the user (S101), and whether or not the internal memory 121 has a free area used for analyzing the message body and displaying the graphic image for a predetermined reference character number set in advance. Is determined (S102). If there is no free space, the number of reference characters is changed to be reduced (S103). The reference character number is set in advance in consideration of the capacity of the internal memory 121 incorporated in the mobile phone 10. For example, the predetermined reference character number is set to 150 characters.

  Next, when the setting of the reference character number is completed, the main control unit 120 determines whether or not the number of characters in the message body of the display target mail is greater than a predetermined reference character number (S104). Here, when the number of characters in the message body is larger than the reference character number, the portion larger than the reference character number is omitted, and information indicating that the mail is halfway at the end (for example, “... The number of characters in the message body of the display target mail is reduced and the end process is performed so that (continuous) is added (step 105). On the other hand, if the number of characters in the message body is less than or equal to the reference number of characters, the character number reduction / end processing is not performed.

  Next, the main control unit 120 starts content analysis and display on the display unit 125 for the message text of the display target mail (S106). As shown in FIGS. 5A to 5E, the message text is displayed so that characters flow while being sequentially added from the top. If the additional display character portion consisting of one or more characters that are additionally displayed in the message body corresponds to the predetermined keyword (Yes in S107), a graphic image (three-dimensional animation image) corresponding to the keyword is displayed. ) Are sequentially displayed on the message body (S108). As shown in FIG. 5A, when the text “Ohayo” in the message body is hit, a three-dimensional animation image with the sun as a motif is superimposed and displayed in front. Then, after the display of the three-dimensional animation image of the sun is completed, the above “Ohayo” is additionally displayed in the message body. As shown in FIG. 5B, when characters that do not correspond to the keyword are displayed, the display of the message text is continued without displaying the graphic image (three-dimensional animation image). As shown in Fig. 5 (c), when the emoticon “(^ o ^) /” in the message body hits, a 3D animation image with the emoticon “(^ o ^) /” in the foreground appears in the foreground. It is enlarged and displayed overlaid. Then, after the display of the 3D animation image of the emoticon is completed, the original emoticon “(^ o ^) /” is additionally displayed in the message body. Also, as shown in FIG. 5D, when a train pictogram in the message text is displayed, a 3D animation image designed in a three-dimensional manner so as to make the train appear three-dimensionally is enlarged on the front. Is displayed. Then, after the display of the three-dimensional animation image of the train is finished, pictograms obtained by reducing the three-dimensional animation image of the train are additionally displayed in the message body.

  The enlarged display of the graphic image (three-dimensional animation image) is continued for a preset display time, and when the display time elapses, a message text additional display screen is displayed. The additional display of the message body after the graphic image is displayed is performed as follows. If the keyword corresponding to the graphic image that has been overlaid as shown in FIG. 5A or FIG. 5C is a text character or emoticon, the original character is additionally displayed as it is in the message body. On the other hand, if the keyword corresponding to the graphic image displayed in an overlapping manner as shown in FIG. 5D is a pictograph, a pictograph obtained by reducing the enlarged graphic image (three-dimensional animation image) is added to the message body. Is displayed. FIG. 5E shows a screen when the graphic mail display is completed for the entire message body to be displayed.

  The analysis and display of the message body is continued up to the preset reference character number (S107 to S110). FIG. 5E shows a screen when the graphic mail display is completed. When the message text of the reference number of characters cannot be displayed on one screen, display control is performed so that the screen is automatically scrolled so that the additionally displayed character portion can be seen.

  As described above, according to the present embodiment, it is determined whether or not a predetermined keyword is included in a message body such as an incoming mail. If the keyword is included, a graphic image corresponding to the keyword is included in the message body. Overlapping display. As a result, it is possible to display a mail with a taste of displaying a graphic image according to the content of the message body of the mail. In addition, regardless of the length of the message body of the email, whether or not the keyword is included and the graphic image are displayed for a predetermined number of characters from the beginning of the message body. Therefore, regardless of the length of the message body, the data storage area used for the above determination and display processing can be reduced to a predetermined size or less, and an email display with an elaborate display of graphic images can be reliably performed.

  In addition, according to the present embodiment, as the graphic image, an animation image, a three-dimensional image, or a three-dimensional animation image that is a combination thereof is displayed, so that the content display of the message body of the mail has a change or a three-dimensional effect. It is possible to display a more elaborate message body.

  In addition, according to the present embodiment, characters are displayed so as to flow while sequentially adding the message body from the beginning, and when the additional display character portion corresponds to a predetermined keyword, the graphic image corresponding to the keyword is displayed as the message body. By displaying the images one after another, it is possible to display a more elaborate message body.

  Further, according to the present embodiment, when the predetermined keyword is a pictogram that is made up of code data and can easily grasp the content specified by the mail sender with one character, the keyword, the graphic image, And whether or not the additional display character corresponds to the keyword can be easily determined.

  Further, according to the present embodiment, when the superimposed display of the graphic image is ended, when the character corresponding to the graphic image is a pictograph, the pictograph in the message body is replaced with a pictograph obtained by reducing the graphic image, By displaying the message body, it is possible to make a fancy in displaying the text of the message body. Further, when the character corresponding to the graphic image is a text character or an emoticon, the message body is displayed as it is, and there is a big discrepancy with the original message body transmitted from the sender side. It can be prevented from occurring.

  Further, according to the present embodiment, with respect to a plurality of keywords indicating similar appearances or concepts, by associating a single graphic image representing them, various keywords can be set in advance, so that the message text While achieving the graphic image display function according to the contents, the number of graphic images used for the display function can be reduced.

  In the control example of FIG. 4 in the above embodiment, an analysis is performed to check whether or not the additional display character portion corresponds to the keyword while additionally displaying the message body. As shown in FIG. Prior to the display of the text, the above analysis may be performed in advance on the entire message text to be displayed (S206). In this case, graphic image display data such as the type of graphic image to be displayed and its display timing are stored based on the analysis result of the message body. When the main body of the message is additionally displayed, the main control unit 120 refers to the temporarily stored graphic image display data and controls to display the graphic image at a predetermined display position (S207 to S211). ). In this case, after starting the display of the message body, it is not necessary to analyze the message body, and the display of the message body accompanied by the display of the graphic image when the predetermined keyword is present can be performed more smoothly. it can.

  Further, in the above embodiment, when various pictograms are included in the predetermined keyword and at least one pictogram exists in the message body to be displayed, the reference character count is set based on at least one of the number and type of the pictograms. The number of reference characters may be set to a more appropriate value by resetting.

  FIG. 7 is a flowchart illustrating control when resetting the reference character number based on the number of pictograms included in the message body. In the case of this control example, when receiving a mail display instruction from the user (S301), the main control unit 120 counts the number of pictograms included in the message body (S301), and according to the counted number of pictograms, Control is performed so that the number of reference characters is changed from the initial setting (S303). For example, when the number of pictograms is 5 or less, the reference character number is kept at the initial setting, and when the number of pictograms is more than five, the reference character number is changed according to the number. Note that the control after changing the number of reference characters according to the number of pictographs is performed, for example, in the same manner as in the case of FIG. 4 or FIG. Also, depending on the type of the pictogram, the memory consumption at the time of display may be relatively large. For example, in the case of a pictograph in which the original pictograph itself moves, the amount of memory consumption is larger than that of a still picture type pictograph. Therefore, the number of reference characters may be changed according to the type of pictogram.

In the above embodiment, the display of the message body with the display of graphic images when there is the predetermined keyword, not only when displaying received mail, flop review display before sending the mail created Or to display sent mail in the send mailbox.

  In the above embodiment, the user may arbitrarily set when to execute the graphic mail display mode. For example, when displaying received mail, as described above, only unopened received mail is displayed in the graphic mail display mode, always displayed in the graphic mail display mode, and always displayed in the normal mail display mode. Any of the above may be arbitrarily selected by the user. Here, the normal mail display mode is a mail display mode that does not involve display of a graphic image corresponding to a keyword in the message body.

  FIG. 8 is an explanatory diagram showing an example of screen transition when the mail display mode is initially set when the received mail is initially opened. After receiving the mail display instruction input by the user on the received mailbox screen 112A, the main control unit 120 switches to the graphic mail display mode or the normal mail display mode when the display effect setting by the user is not made. Control is performed to display a display effect setting screen 112 </ b> B for selecting one of them. In the present embodiment, the graphic mail display mode is selected as the initial setting as shown on the screen 112B in FIG. When mail is displayed after setting the display effect, the display mode is selected based on the setting, and the mail is displayed.

FIG. 9 is an explanatory diagram showing an example of screen transition when the user resets the display effect after the initial setting of the display effect. When “display effect setting” is selected on the general mail setting screen 113A, a display effect setting screen 113B is displayed. On the display effect setting screen 113B, the user can arbitrarily set one of the following three types of settings.
(1) “Always display graphic mail”: When displaying the mail message body, always display in the graphic mail display mode.
(2) “Display graphic mail only when unopened”: Displayed in the graphic mail display mode only when displaying the message body of an unopened received mail. When displaying the message body of another mail, it is displayed in the normal mail display mode. In the initial state before the setting is changed by the user, this “graphic mail display only when not opened” is set.
(3) “Always display normal mail”: When displaying the message body of the mail, always display in the normal mail display mode.

  Further, as shown in FIG. 10, when “always display graphic mail” or “display graphic mail only when unopened” is set, the background color when displaying graphic mail may be set. For example, in the example of FIG. 10, an arbitrary color can be selected from “white”, “light blue”, “yellow”, “rose”, “green”, and “blue” as the background color. The color of the character is selected according to the background color. When the graphic mail display mode is set, the drawing speed for displaying the message text in the graphic mail may be set. For example, an arbitrary drawing speed may be selected from three stages of “standard”, “high speed”, and “low speed”. When setting the background color and drawing speed, it is preferable to preview the sample mail so that the graphic mail display after the setting can be confirmed.

  Further, it may be possible to set whether to display in the graphic mail display mode or the normal mail display mode for each mail to be displayed or for each mail type. Further, for each mail storage location (for example, a mailbox), it may be possible to set whether to display in the graphic mail display mode or the normal mail display mode.

  Table 2 shows a setting example for setting the mail display mode for each mailbox. The column of the mail opening operation in Table 2 is a setting for opening and displaying the mail from the mail box list display screen. In the case of this operation, graphic mail display is performed for the inbox according to a predetermined condition set in advance. That is, in the initial setting state, an unopened received mail is displayed in the graphic mail display mode, and an unopened received mail is displayed in the normal mail display mode. Other mailboxes are displayed in the normal mail display mode. The graphic mail display operation column from the menu in Table 2 is a setting for displaying graphic mail from the menu on the screen displaying mail in the normal mail display mode. In the case of this operation, graphic mail is displayed according to the user's selection conditions in the menu. A graphic mail is also displayed for the message body of the mail being edited according to the selection condition of the user in the menu.

  FIG. 11 is an explanatory diagram of screen transition when previewing the message body being edited in the graphic mail display mode. When a menu is selected on the mail editing screen 115A, a menu selection screen 115B is displayed. When the graphic mail preview is selected on the menu selection screen 115B, the message body being edited can be displayed in the graphic mail display mode as shown in the graphic mail display screen 115C.
